This is pretty much the last issue I need to iron out with my car. Temp will not change on the sensor. I had a spare so i popped that one in and same thing. Im assuming i need to just trace wires and verify everything to ecu but how crucial is this? Will this greatly effect things or can I get away with it until I have more time to dig in deeper.

I believe I had to change something I. Ecmlinm to get it working properly.
I found the answer through forums. Let me see if I can find it again.
I bought a new iat thinking that would fix it too but that wasn't the issue.

You should go to your ecu inputs page in the log and select the lock iat and baro pressure. your not running the stock maf so those have to be locked. it's set at 77 degrees so the ecu see's a safe number and doesn't throw a check engine light.
if you want to see the actual intake temp you'll have to capture gm iat and then put it in the display.
